The American film industry changed beyond recognition after the milestone year of 2001, director Oliver Stone told RT, with producers using financial restraints to censor movies challenging the US military or the CIA.

"Maybe in the 1980s, when I did 'Platoon', 'Born on the Fourth of July' and 'Heaven & Earth', I could do that, because it was a slightly more relaxed system," said the award-winning filmmaker, mentioning his famed movies while making his case during former Ecuadorean President Rafael Correa's show on RT Spanish.

When the Iron Curtain fell and the Cold War ended, things didn't change for the better, Stone believes. "My film career has suffered, because sometimes I've said things that American producers hate to hear," he revealed, adding that those sponsoring film productions sometimes resort to "economic censorship."
